摘要：

采用灵芝和平菇菌丝分别与果树、杨木和竹材为主的植物碎料设计成型六种生物泡沫（依次标记为GG、GY、GZ、PG、PY、PZ），对其防火特性进行研究。结果表明：生物泡沫GG、PY的成炭率较高，阻燃性能较好；在33 s后达到热释放速率峰值，为（204.46±11.38） kW/m2，总热释放量随时间呈现先快后慢的趋势，540 s之后CO产生量迅速增大，该生物泡沫表层菌丝体有较好的阻燃作用，在燃烧初期产生明显的烟气。菌丝体生物泡沫的防火特性与保温泡沫性能相当甚至更优，但阻燃性能有待进一步提升。

Abstract:

 Six kinds of bio-foams (labeled as GG, GY, GZ, PG, PY and PZ successively) were designed and fabricated by using the mycelium of Ganoderma lucidum and Pleiatus ostreatus with the plant debris mainly composed of fruit trees, poplar and bamboo, and the fire resistance characteristics were studied. The results showed that, the carbon formation rate and flammability of bio-foam GG and PY were preferable. After 33 s, the heat release rate reached the peak value of (204.46±11.38) kW/m2. The total heat release showed a trend of fast to slow with time. After 540 s, the production of CO increased rapidly. And the smoke production was evidently at initial phase for the antiflaming of mycelium. The fire resistance of mycelium bio-foam is comparable to or even better than that of general thermal insulation foam, and its flame retardancy needs to be improved furtherly.
